In the bedroom I have wall mount tv and the behind cabinet doors I have Directv dvr, audio receiver, blue ray and firetv. I have been using a harmony with hub but it is hit and miss with the signals inside the cab. I replaced the harmony irís with some singles ones I had to mount to each component but it seems worse now. I guess since the are not Logitech brand they are messing up the mix. Any ideas for something that would work. Thanks Michael
